Ni/NiO hybrid nanostructure supported on biomass carbon for visible-light photocatalytic hydrogen evolution

Structure Sensitivity in Hydrogen Adsorption on Ni/NiO Interfaces for the Hydrogen Evolution Reaction

“…Undoubtedly, both charge competition and Coulomb repulsion would weaken the adsorption, leading to an increase in Δ G H . This explanation not only clarifies why certain sites near the boundary O lose their ability to adsorb the hydrogen in our interface models but also sheds light on the increase in Δ G H observed in previously proposed models such as the partially oxidized model − and the O-oriented NiO(111) belt model …”

Plasma-Catalytic Process of Hydrogen Production from Mixture of Methanol and Water

“…In the presence of water this is no surprising. Water can be decomposed on nickel catalysts and nickel can be oxidized [57] The presence of nickel oxide may be advantageous because it makes the photochemica reactions run more efficiently [58]. Other metal oxides are photo-catalysts, on which th water splitting process takes place [59,60].…”

Visible-light driven H2 evolution over a precious metal-free hybrid photocatalyst constructed from CuO and NiFe layered double hydroxide

“…The result agreed with that suggested in a recent computational work, in which NiO (111) hardly produces H 2 in the HER process. 51 In contrast, the hydrogen adsorption free energy of CuO (111) was only −0.62 eV, indicating that the process of H 2 production on CuO (111) was more facile. The other surfaces including NiFe LDH (003) and NiFe 2 O 4 (311) exhibited a moderate Δ G H* of −0.75 eV and −1.03 eV, respectively.…”
